chain sprocket single-phase Induction Motors
The single-phase electric motor operates beneath the same principle as the polyphase motor, except that the rotating magnetic field effect produced by the stator does not exist until running rpm is reached. Since no starting torque is available, a design mechanism is included to begin the motor. They are the various designations:
Torque-Speed Curves of Different Single-Phase Induction Motors
Shaded-pole: Have only one main winding and no start winding. This configuration causes a change of the used magnetic field in relationship to the rotor, creating stating torque. Applications include enthusiasts and small appliances.
Split-Phase (induction start motor)
Has two models of stator windings. The “start” windings are positioned 90 degrees to the “run” windings and shift the magnetic field of the stator, inducing beginning torque. Applications include little grinders, small supporters, and blowers.
The most typical single-phase motor used in industrial applications. It really is a altered split-stage engine with a capacitor in series with the beginning winding to supply a start boost. App include small conveyors, huge blowers, pumps, and direct-drives.
Uses identical main and auxiliary windings with a capacitor to supply starting torque. They are the most reliable single-phase engine because no centrifugal starting switch is required. Applications include supporters and pumps in HVAC and refrigeration industries.
